Dangerous Goods Classifications

Nine Classes Based on Hazard Type– Class 1: Explosives– Class 2: Gases– Class 3: Flammable Liquids– Class 4: Flammable Solids– Class 5: Oxidizers– Class 6: Poisons– Class 7: Radioactive

Materials– Class 8: Corrosives– Class 9: Miscellaneous

How to Classify Dangerous Goods

• Step 1: Determine if material is exempt– Refer to Part II (Section 2.3) of TDG

Regulations to determine if exempt. If so, classification is not required.

• Step 2: Determine Classification– Refer to Schedule II of TDG

Regulations. • List I consists of explosive materials. • List II consists of more than 3000

dangerous goods, other than explosives.

Exemptions

• Gasoline & Diesel Fuel– TDGR Section 2.31 makes partial

exemptions for transportation by road if:• Containers are transported in open

vehicle so label or placard is visible from outside the vehicle;• Each container is secured to the

vehicle during transport; and• Total capacity of containers in/on

vehicle is not more than 2,000 liters.

sulfur dioxide

Class 2: Gases• Hazards– Explosion or fire– Container rupture– Container rocketing– Frostbite– Asphyxiation– Toxicity– Irritation

Class 3: Flammable Liquids

• Liquids with a flash point < 61deg C

• Commonly used as fuels – Gasoline, fuel oil, diesel

• Flash Point– Minimum temperature at which a

liquid gives off sufficient vapour to form an ignitable mixture with air at the surface of the liquid.

Class 3: Flammable Liquids

• Hazards– Fire– Explosions– Toxic fumes– Corrosivity– Water contamination

DANGER

Compatibility

• Segregation of Incompatible Materials– TDGR have requirements and

prohibitions for transporting incompatible materials (see Compatibility Chart) on the same vehicle.

– Examples:• Liquid fuels may be transported with

propane• Propane & herbicides can only be

transported together if separated such that leakage will not impact the other material

• Liquid fuels must not be transported with herbicides/pesticides

Reading a Numbered Placard

48

• Numbered placards may better identify contents by using the United Nations, or UN, ID number

For:• Tank cars• Cargo tanks• Portable tanks• Other bulk packaging
